3 Claim. (CI. 34-26) This invention relates to an improved bottleinspecting device and more particularly to a compressed air brush forremoving fluid from the exterior of bottles.

6 In my application Serial No. 133,992, filed March 31, 1937,.1 describeand claim an improved optical system for examining the fluid contents ofbottles and which is particularly adapted for use with fluted bottlessuch as are often used for 10 containing carbonated beverages.

such apparatus it has been found that freshly fllled bottles often havewater or portions of the liquid with which they have been fllledadhering to their exterior surfaces, and when the bottle 15 is examined,these drops of fluid produce the effect of foreign material within thebottle. The present invention relates more particularly to means forremoving this fluid from the exterior of the bottle.

At one stage of the handling of the bottle in an inspecting machine thebottle is whirled very rapidly, and in order to remove fluid from theexterior of the bottle, I apply thereto, while the bottle is beingwhirled, a jet of air at high .velocu ity. This, in cooperation with thecentrifugal force produced by the whirling of the bottle, removes anysurface fluid practically instantly and permits accurate inspection ofthe bottle.

One object of my invention is to 'provide an improved means for removingfluid from the exterior surface of bottles.

Another object of my invention is to provide means for removing fluidfrom the exterior surface of bottles without interfering with the op-'eration of a bottle inspecting machine.

Another object of my invention is to provide such a device which can bereadily incorporated in a bottle inspecting machine or other bottlehandling device.

o Other and incidental objects of my inventionwillbeapparenttothoseskilledintheartfrom areadingofthefollowingandinspection of the accompanying drawing in which In theuse of Figure 1' is a transverse section through a modifled form oftheinvention, and

Figure 2 is an elevation of the device shown in la. 1.

In the form. of the invention shown in Fig. 1 6 a nozzle 30 is providedwhich, as shown in Pig. 2, is shaped to correspond to the externalconfiguration of the bottle. Compressed air is supplied through a pipeii and this is directed in the form of a thin sheet at a high velocityagainst the surmv face of the bottle. As indicated in Fig. 1, the nozzleis directed substantially tangentially toward the bottle at oppositionto the direction of rotation so that the action of the compressed airand centrifugal force cooperate to blow the particles 15 of waterradially away from the bottle. An exhaust nozzle 32 may be providedconnected to an appropriate exhaust fan for withdrawing the water blownfrom the bottle and preventing its being spattered on other parts of themachine. In 20 this form of the invention the. homes are located at thestations where it is desired to remove the water from the bottle and.the bottles are moved past the nozzles.

Having now described my invention, I claim: as 1. A bottle inspectingdevice including means for rapidly whirling a bottle and means fordirecting a' stream of air at high velocity tangentially against saidbottle while it is being whirled.

2. A bottle inspecting device including means so for whirling the bottleand means for directing a stream of air tangentially th in a directionopponte to the direction of rotation while the bottle is being whirled.

3. A bottle inspection device including means 35 for rotating thebottle, means adapted to direct 'a stream of air tangentially th in adirection opposite to the direction-of said rotation for removing-liquidfromthesurfaceofsaidbottle,andmeansforremovingsaidliquidfromthe uvicinityofsaidbottle.
